Spammers who "did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA"
[This message has also been posted to comp.mail.sendmail.]
My mailserver gets a lot of errors reported such as:
Oct 1 11:49:36 ak74 sendmail[31464]: l91Gnatt031464: nat.incompany.ru [83.167.0.4] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
Oct 1 11:49:37 ak74 sendmail[31460]: l91GnXOc031460: [59.92.187.94] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
Oct 1 11:50:40 ak74 sendmail[31647]: l91Goe5W031647: pool-71-125-52-61.nycmny.fios.verizon.net [71.125.52.61] did not issue MAIL/EXPN/VRFY/ETRN during connection
to MTA
These errors are clearly spammers trying to send me spams. I would
like to know if there is some extension that would quietly junk all
these spams with as little CPU spent on them. I do not want to log
them, save them anywhere etc. Ideally, sendmail would either issue a
500 error or just quietly junk these messages.
I would prefer this done before queuing them locally and without invoking spamassassin.
Any extension for this?
thanks

There's no mail to discard. The client connected and disconnected
without doing anything (to send mail or harvest an address).
